ucg and gtl scoping study, page-5

Just to clarify and avoid any confusion - the company is looking at the technology which carbon energy are using, the LNC videos were posted for diagrammatic purposes only.

A video can be viewed at the CNX website, however it does not have a great deal of technical information behind it.

Secondly a breakdown of the two procedures for UCG is as follows:

"The first, based on technology from the former Soviet Union, uses vertical wells and a 'reverse' combustion to open up the internal pathways in the coal. The process has been tested (1999-2003) in Chinchilla, Australia using air and water as the injected gases.The second, tested in European and American coal seams, creates dedicated in-seam boreholes, using drilling and completion technology adapted from oil and gas production. It has a moveable injection point known as CRIP (controlled retraction injection point) and generally uses oxygen or enriched air for gasification."
